"I think to be honest I was not playing too bad for these two matches," Rublev said of his two matches at the International Tennis Stadium at Zayed Sports City. <strong>_____________________</strong> <strong>Read more:</strong> <strong>_____________________</strong> Rublev, who reached the quarter-finals at the US Open in September, said he had found the warmer UAE weather a challenge having done all of his pre-season training in colder climes. "I was playing quite well for these conditions, especially as I arrived only one day before the match starts," he said. "So I don't really have time to adapt to these conditions. Different weather which was so humid as I was doing off-season in the cold weather, so it was completely another feeling." The first set was a tight encounter as serve initially dominated, but Rublev's fierce groundstrokes were constantly putting Carreno Busta on the backfoot. A single break of serve was enough to take the first set and he ran away with the second set with a further two breaks.
